% graphviz - Haskell bindings to the Graphviz toolkit

The graphviz Library
====================
The _graphviz_ library provides bindings to the [Graphviz] graph
visualisation suite of tools for the purely functional programming
language [Haskell]. It can be downloaded from [HackageDB] or - if you
have [cabal-install] - installing it is as simple as:
~~~~~~~~~~~~~~~~~~~~ {.bash}
cabal update
cabal install graphviz
~~~~~~~~~~~~~~~~~~~~

Library features
----------------
Main features of the graphviz library include:
* Almost complete coverage of all Graphviz attributes and syntax.
* Support for specifying clusters.
* The ability to use a custom node type.
* Functions for running a Graphviz layout tool with all specified
output types.
* The ability to not only generate but also parse Dot code with two
options: strict and liberal (in terms of ordering of statements).
* Functions to convert [FGL] graphs and other graph-like data
structures to Dot code - including support to group them into
clusters - with a high degree of customisation by specifying which
attributes to use and limited support for the inverse operation.
* Round-trip support for passing an [FGL] graph through Graphviz to
augment node and edge labels with positional information, etc.
